PVA 098-27 Application
PVA 098-27 is a medium-viscosity, fully hydrolyzed polyvinyl alcohol characterized by low foaming tendency, favorable fluidity, and delicate film-forming capability, serving as a multipurpose material for diverse high-end industrial scenarios.
- Fabric Sizing Materia: A low-foaming high-performance warp sizing additive. It reinforces yarn tensile strength and guarantees stable running conditions during weaving.
- Fabric Finishing Agent: Modifies textile properties to improve fabric flatness, rigidity, and dimensional stability, catering to high-grade textile surface-finishing demands.
- Paper Surface Sizing: Boosts paper surface strength, water resistance and overall printability.
- Paper Pigment Binder: Stabilizes coating pigments evenly, lifting paper surface smoothness and surface gloss.
- Paper Adhesive: Environment-friendly high-adhesion raw material for lamination and compositing of paper packaging products.
- Emulsifier: Low-foaming protective colloid and stabilizer suitable for PVAC and acrylic emulsion polymerization.
- PVA Film: Used to manufacture industrial functional films with superior surface flatness and mechanical toughness.
- Thermosetting Resin Modifier: Elevates the toughness of cured resin, lessens brittleness and cracking risks, and cuts free formaldehyde content for greener resin formulas.
- Dispersant: Low-foaming dispersing agent for inorganic pigments, fillers, and industrial fine powders to avoid particle agglomeration.
- Coating & Glue: Minimizes bubble defects, optimizes coating leveling performance, and improves long-term stability of water-based adhesives.
